The dark side of vitamin D supplementation

虽然预防维生素D缺乏很重要，但关于维生素D的最佳摄入量和浓度存在争议。我们的目的是评估对维生素D剂量的安全担忧维生素D通常被推广为无监督的公众使用的非处方产品。为此，我们将评估婴儿补充维生素D对健康的长期影响，并利用遗传学方法评估高维生素D和高钙浓度的因果关系。

While is important to prevent vitamin D deficiency, controversies exist about optimal vitamin D intakes and concentrations. Our aim is to evaluate safety concerns with dosages of vitamin D which are routinely promoted for unsupervised public use with over the counter products. We will do this by evaluating long-term health effects for infant vitamin D supplementation, and by using a genetic approach to evaluate the causal effects of high vitamin D and calcium concentrations.
